Abstract

The invention belongs to the technical field of surrounding rock monitoring, and discloses an anchor rod. The anchor rod includes an anchor rod body, a supporting tray and an anchor rod head, the anchor rod body is internally provided with a cavity, distributed sensor fibers are distributed in the cavity, the supporting tray sleeves the anchor rod body and is locked through the anchor rod head. According to the anchor rod, strain continuous monitoring can be realized based on the support function of the anchor rod, and thus reliable judgment of the stability of surrounding rock is realized.

Description

technical field [0001] The invention relates to the technical field of surrounding rock monitoring, in particular to a method for continuous monitoring of bolt and surrounding rock strain. Background technique [0002] In the field of mineral mining, it is necessary to monitor the reinforcement effect and stability of the surrounding rock in real time to control safety risks. In the prior art, parameters such as strain of the surrounding rock are collected by way of sensor arrangement, and are used to judge the stability of the surrounding rock. Usually, sensors based on strain gages are used to disperse the distribution points. This discrete distribution method can obtain a large range of data, but often the data are scattered at each point, and the overall continuous strain change cannot be detected, resulting in inaccurate evaluation results. reliable. Contents of the invention [0003] The invention provides a continuous monitoring method for anchor rods and surround...
